[hibernate-issues] [Hibernate-JIRA] Updated: (HHH-5339) Restrictions.ilike doesn't work on integer columns

Restrictions.ilike doesn't work on integer columns -------------------------------------------------- Key: HHH-5339 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5339 Project: Hibernate Core Issue Type: Bug Reporter: Chris Wilson Attachments: HibernateCriteriaLikeIntegerTest.java Hibernate doesn't like using {@link Restrictions#ilike} on integer columns. It uses the SQL lowercase function on the column, the result of which must be a character type (CHAR or VARCHAR) because: bq. LOWER Converts a string to all lowercase characters ([SQL in a Nutshell|http://oreilly.com/catalog/sqlnut/chapter/ch04.html]) But IlikeExpression.getTypedValues() asks the criteria query for the type of the typed values, which returns the underlying type, which in this case is an integer type. Hibernate then throws a ClassCastException, trying to fit the string parameter into an Integer TypedValue: * java.lang.ClassCastException: java.lang.String cannot be cast to java.lang.Integer * at org.hibernate.type.IntegerType.set(IntegerType.java:64) * at org.hibernate.type.NullableType.nullSafeSet(NullableType.java:154) * at org.hibernate.type.NullableType.nullSafeSet(NullableType.java:136) * at org.hibernate.loader.Loader.bindPositionalParameters(Loader.java:1732) * at org.hibernate.loader.Loader.bindParameterValues(Loader.java:1703) * at org.hibernate.loader.Loader.prepareQueryStatement(Loader.java:1593) * at org.hibernate.loader.Loader.doQuery(Loader.java:696) * at org.hibernate.loader.Loader.doQueryAndInitializeNonLazyCollections(Loader.java:259) * at org.hibernate.loader.Loader.doList(Loader.java:2232) * at org.hibernate.loader.Loader.listIgnoreQueryCache(Loader.java:2129) * at org.hibernate.loader.Loader.list(Loader.java:2124) * at org.hibernate.loader.criteria.CriteriaLoader.list(CriteriaLoader.java:118) * at org.hibernate.impl.SessionImpl.list(SessionImpl.java:1597) * at org.hibernate.impl.CriteriaImpl.list(CriteriaImpl.java:306) * at org.wfp.rita.datafacade.RequestDao.listRequests(RequestDao.java:736) I can't give you a patch because I can't build Hibernate because the actual instructions are missing from [http://www.hibernate.org/sourcecode.html]. I'll attach the test in a second.
